Well I have ventured forth on my tranny problem and have an update to share. As you can see, I did not get any replies to my original question about removing the retaining pin for the manual linkage and took that to mean nobody had any sage advice to share. I now know that it was because nobody wanted to wast time replying with "Duh!". To provide a little background, before digging into my linkage repair I searched around for any information about how to get things out properly. Among the posts I saw was one on an Explorer site (they use the same 5R55S trans) where the guy ended up drilling out the pin. Another post talked about having to somehow use a slide hammer on the thing. I also saw a tool for $65 to help get them out. ??? Anyway, when I first got under there I grabbed hold of the pin with a good pliers and it didn't budge. I had to quit for other reasons at that time, so I later posted the question above based on what I'd seen and experienced. Cut to last night, one of 2 this week with double digit temps here, and got ready for what I was sure was going to be a battle. I didn't want to spend the $$ on that tool so I was gonna see what I could accomplish. I clamped my best vise grips on the 1/8" of pin showing and gave it a tug to see if the pliers were on right, and the stupid damned pin came right out!!! FYI to anyone needing to replace the detent 'rooster tail', removing the pin allows the shaft to move, but you will still need to remove the switch on the outside of the trans to move far enough to get the detent on. It will take a long flat 8mm wrench and a lot of patience to get the switch bolts off unless you have a dexterous three year old around who can get their tiny hands up in there. Also, make sure the park rod is seated properly (no clips or hooks but it has to mate up to the parking pawl in the tail shaft) and the shift lever shaft is properly aligned when you put the detent on. You probably can't get the detent on the shaft without seating the park rod properly, but I can see where you could get the lever shaft off 180 degrees and then the shifter probably wouldn't work right.
